I Compromised By Subtracting Thirty-One Seconds From The Total Of My Chronometer's Losing Error, And Sailed Away For Tanna, In The New Hebrides, Resolved, When Nosing Around The Land On Dark Nights, To Bear In Mind The Other Seven Miles I Might Be Out According To Captain Wooley's Instrument.

Tanna lay some six hundred miles west- southwest from the Fijis, and it was my belief that while covering that distance I could quite easily knock into my head sufficient navigation to get me there.

Well, I got there, but listen first to my troubles. Navigation IS easy, I shall always contend that; but when a man is taking three gasolene engines and a wife around the world and is writing hard every day to keep the engines supplied with gasolene and the wife with pearls and volcanoes, he hasn't much time left in which to study navigation. Also, it is bound to be easier to study said science ashore, where latitude and longitude are unchanging, in a house whose position never alters, than it is to study navigation on a boat that is rushing along day and night toward land that one is trying to find and which he is liable to find disastrously at a moment when he least expects it.

To begin with, there are the compasses and the setting of the courses. We sailed from Suva on Saturday afternoon, June 6, 1908, and it took us till after dark to run the narrow, reef-ridden passage between the islands of Viti Levu and Mbengha. The open ocean lay before me. There was nothing in the way with the exception of Vatu Leile, a miserable little island that persisted in poking up through the sea some twenty miles to the west-southwest - just where I wanted to go. Of course, it seemed quite simple to avoid it by steering a course that would pass it eight or ten miles to the north. It was a black night, and we were running before the wind. The man at the wheel must be told what direction to steer in order to miss Vatu Leile. But what direction? I turned me to the navigation books. "True Course" I lighted upon. The very thing! What I wanted was the true course. I read eagerly on:

"The True Course is the angle made with the meridian by a straight line on the chart drawn to connect the ship's position with the place bound to."

Just what I wanted. The Snark's position was at the western entrance of the passage between Viti Levu and Mbengha. The immediate place she was bound to was a place on the chart ten miles north of Vatu Leile. I pricked that place off on the chart with my dividers, and with my parallel rulers found that west-by-south was the true course. I had but to give it to the man at the wheel and the Snark would win her way to the safety of the open sea.
